Fissile Locks [PDF]

arXiv, 2020
Classic test-and-test (TS) mutual exclusion locks are simple, and enjoy high performance and low latency of ownership transfer under light or no contention. However, they do not scale gracefully under high contention and do not provide any admission order guarantees.

Hydrodynamic Synchronisation of Model Microswimmers

, 2009
We define a model microswimmer with a variable cycle time, thus allowing the possibility of phase locking driven by hydrodynamic interactions between swimmers.

Expression and purification of E140 protein antigen fragments of Plasmodium vivax and Plasmodium berghei for serological assays

FEBS Open Bio, EarlyView.
We provide a step‐by‐step guide for producing E140 antigen fragments from Plasmodium berghei (Pb1) and Plasmodium vivax (Pv1). Pb1/Pv1 are expressed in E. coli, solubilized by freeze–thawing, refolded by slow dilution, purified by affinity chromatography (IMAC), then concentrated and subjected to quality control.

Distributed Consistency Method and Two-Phase Locking in Cloud Storage over Multiple Data Centers

Cybernetics and Information Technologies, 2015
In replication management under multi-datacenter cloud storage environments, the problem of a replica being inconsistent across multiple datacenters must be solved.

Huyghens, Bohr, Riemann and Galois: Phase-Locking

, 2005
Several mathematical views of phase-locking are developed. The classical Huyghens approach is generalized to include all harmonic and subharmonic resonances and is found to be connected to 1/f noise and prime number theory.

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

FEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

Compensation characterization of the UPQC system under an improved nonlinear controller based on the MSTOGI-PLL device

Frontiers in Energy Research
To solve the delay problem of a unified power quality conditioner (UPQC) system during the separation of the fundamental positive-order components and to better filter out the DC and harmonic components to realize accurate phase locking, a mixed second ...

Injection locking and parametric locking in a superconducting circuit [PDF]

Phys. Rev. Applied 12, 024034 (2019), 2019
When a signal is injected in a parametric oscillator close enough to its resonance, the oscillator frequency and phase get locked to those of the injected signal. Here, we demonstrate two frequency locking schemes using a Josephson mixer in the parametric down-conversion regime, pumped beyond the parametric oscillation threshold. The circuit then emits

Anti-phase locking in a two-dimensional Josephson junction array

, 1996
We consider theoretically phase locking in a simple two-dimensional Josephson junction array consisting of two loops coupled via a joint line transverse to the bias current.
